Hi all,

Some more news about this. I discovered that since installing that patch,
named is eating 99% of CPU and is also using a lot of bandwith (about 250 Mb
in 5 hours).

When I stop it, bandwith problems stop but email stop working. also in my
var/log/messages, I get :

Jun 28 11:31:53 ns named[1140]: Cleaned cache of 0 RRsets
Jun 28 11:31:53 ns named[1140]: USAGE 993724313 993717113
CPU=6905.13u/99.71s CHILDCPU=0u/0s
Jun 28 11:31:53 ns named[1140]: NSTATS 993724313 993717113 A=39610 NS=4865
PTR=493684 ANY=30374
Jun 28 11:31:53 ns named[1140]: XSTATS 993724313 993717113 RR=280532 RNXD=0
RFwdR=4791 RDupR=275155 RFail=16 RFErr=0 RErr=0 RAXFR=0 RLame=0 ROpts=0
SSysQ=28 $

The part I am worried is usually, named says it cleaned the cache for 10 to
30 resets not 0.

If I stop named, the emails are accepted by the server, but are not reaching
the users. If it is on, it says that "550 - there is no such user here"

Any ideas?

I would be looking at something in your DNS that is not configured
correctly - ie; typo, bad cname, etc. To start from scratch on DNS, make a
copy of your /etc/named/records file and remove the original file. You will
need to click on "Save DNS Settings" in control panel to allow DNS to start
from scratch. At this point take a look at DNS and see if it appears to be
running correctly e.g. low cpu, etc. If everything seems fine start entering
(via the gui) some DNS entries for websites and see if sendmail works OR if
it pukes out. This will at least point you in which direction to go in; a)
if sendmail runs fine then the problem was in DNS OR b) if sendmail still
pukes you may need to take a closer look at your sendmail files or logs.
